Research Status of SLAM

SLAM (simultaneous localization and mapping), also known as CML (Concurrent Mapping and Localization), real-time location and map construction, or concurrent mapping and positioning. The main problem is to place the robot in an unknown location in an unknown environment, giving the robot a way to gradually draw a complete environmental map. The robot can avoid obstacles in the room. We have divided the methods of SLAM into several categories including the perspective of sensors, the existing research at home and abroad, the serength and weakness of these research and the tasks of next stage.
